+## AI Description
+The `Juliet::D3D12` module manages DirectStorage 12 descriptor pools and CPU-side handle indexing. It provides thread-safe mechanisms for allocating, assigning, and releasing resource handles across different heap types (RTV, DSV, SRV) to optimize GPU memory access patterns within the Juliet graphics engine.
